Wordpress not storing uploaded files

this is really weird. I am uploading files through the admin interface within Wordpress 3.0.

Wordpress recognizes the file type and attributes, but does not store it within wp-content/uploads succe开发者_如何学Pythonssfully.

Upon upload I am given a url that points to a file within wp-content/uploads, that does not exist.

Are there any common gotchas? I have no clue what this could be caused by :|

Thanks in advance, help would be wonderful.

Ensure your uploads folder writable by PHP and does it exist? Although WordPress should indicate this, it is a common thing.

UPDATE

If the above does work, try setting WP_DEBUG to true in your wp_config.php and see if there are any errors.
